Abstract (en)
[origin: WO9411577A1] The invention relates to a method of producing visible, preferably transparent or translucent, continuous streaks and/or delimited fields in paper in conjunction with forming a paper web in a paper machine. The method is characterized by essentially preventing dewatering of paper stock/paper fibres on one or more surfaces of a wire in the forming unit of a paper machine in conjunction with forming a paper web in the machine, and by applying a special stock that contains fibres which differ from the other fibre material deposited on the wire, optionally together with an arbitrary filler and/or binder. The invention also relates to a valuable document, such as a banknote, produced from the aforedescribed paper.
